Abstract
The invention relates to an artificial hip joint acetabular cup. The artificial hip joint acetabular cup is shaped like a concave semicircle arc, the artificial hip joint acetabular cup comprises an outer layer, an inner layer, an acetabular cup lining and a lining shell, wherein the outer layer and the inner layer are fixed into a whole; the lining shell wraps the acetabular cup lining, the outer side of the lining shell is locked with the the surface of the inner layer, and the inner side of the lining shell is matched with the acetabular cup lining; the inner lining shell is made of polyether-ether-ketone or derivatives of the polyether-ether-ketone. According to the artificial hip joint acetabular cup, the inner layer is combined with the acetabular cup lining through the lining shell which is made of the polyether-ether-ketone (PEEK) or the derivatives of the polyether-ether-ketone, stress concentration is reduced, and the rigidity of the acetabular cup is increased properly; due to the fact that the lining shell which is made of the PEEK or the derivatives of the PEEK wraps the acetabular cup lining and then is combined with the inner layer, the matching requirements of a hard lining can be met, and the matching requirements of a soft lining can be met.
Description
Technical field
The present invention relates to a kind of medical rehabilitation instrument, more specifically, relate to a kind of artificial hip joint mortar cup.
Background technology
Hip cotyle cup prosthesis of new generation generally adopts the design of lining more than a glass in recent years, namely mortar cup can accept soft liner (UHMWPE liner, RiesMD.Reviewoftheevolutionofthecementlessacetabularcup. Orthopedics.2008Dec simultaneously; 31 (12Suppl2) .pii:orthosupersite.com/view.asp? rID=37178.Review.) and hard liner (ceramic-lined, ChotaiPN1, SuEP.Orthopedics.2011Oct5; 34 (10): e682-4.doi:10.3928/01477447-20110826-30.Fractureofatitan iumsleeve-encasedthird-generationceramiclinerinamodernTH A, or metal inner lining).But these two kinds of liners have distinct requirement to closing component structure, wherein soft liner requires outside sphere seamless contact mortar cup inwall as much as possible, thus eliminate water pump effect and ensure inner liner wall maximize thickness, hard liner then require the liner outer ledge conical surface and mortar cup conical surface of inboard wall sealed.
For different patients, the mortar cup being suitable for accepting soft liner had, the mortar cup being suitable for accepting hard liner had, but, for the mortar cup of hard liner, the particularly ceramic-lined distortion to mortar cup and the stress that formed is concentrated responsive especially of hard liner, in order to prevent the excessive mortar cup that causes of the stress of hard liner to mortar cup damaged, often maximizes the rigidity increasing mortar cup by the edge thickness of mortar cup.But such way is not only loaded down with trivial details, and often cause the more high a series of defect of cost of manufacture.
Therefore, the artificial hip joint mortar cup of the hard liner of a kind of acceptance newly expects.
Summary of the invention
For the technical problem of above-mentioned solution, the object of this invention is to provide a kind of artificial hip joint mortar cup.
In order to realize foregoing invention, the present invention adopts following technical scheme:
A kind of artificial hip joint mortar cup, described artificial hip joint mortar cup is inner concave shape semicircle arcuation, comprises skin, internal layer, mortar cup liner and liner overcoat, and wherein said skin and described internal layer are integrally fixed structure; Mortar cup liner described in described liner outer sheath covers, outside and the described internal layer surface of described liner overcoat are sealed, and inner side and the described mortar cup liner of described liner overcoat match; Described liner overcoat is made up of polyether-ether-ketone or derivatives thereof.
Further, described mortar cup liner is hard liner.
Further, described hard liner is ceramic-lined or metal inner lining.
Further, described internal layer surface is standard spherical structure, and described internal layer and described liner overcoat and described mortar cup liner form sliding friction surface.
Further, described internal layer surface is non-uniform spherical structure, and described internal layer and described liner overcoat and described mortar cup liner form assembly type fixed structure.
Owing to adopting above technical scheme, beneficial effect of the present invention is:
1) internal layer in structure provided by the invention passes through liner overcoat and the mortar cup interliner of polyether-ether-ketone (PEEK) or derivatives thereof, reduces stress and concentrates, also suitably add the rigidity of mortar cup.
2) be combined with internal layer again by the liner outer sheath covers mortar cup liner of PEEK or derivant in structure of the present invention, the coupling requirement of hard liner can be met, the coupling requirement of soft liner can be met again.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, an embodiment of artificial hip joint mortar cup provided by the invention, in this embodiment, artificial hip joint mortar cup is inner concave shape semicircle arcuation, comprise outer 1, internal layer 2, mortar cup liner 3 and liner overcoat 4, its ectomesoderm 1 and internal layer 2 are integrally fixed structure; Liner overcoat 4 wraps up mortar cup liner 3, the outside of liner overcoat 4 and internal layer 2 surface sealed, inner side and the mortar cup liner 3 of liner overcoat 4 match; Liner overcoat 4 is made up of polyether-ether-ketone (PEEK) or derivatives thereof.
In the above-described embodiments, mortar cup liner 3 is hard liner; Hard liner preferably ceramic liner.
In the above-described embodiments, internal layer 2 surface is non-uniform spherical structure, and internal layer 2 forms assembly type fixed structure with liner overcoat 4 and mortar cup liner 3.
In addition, the mortar cup liner 3 in artificial hip joint mortar cup provided by the invention also can be the hard liner of metal inner lining; Internal layer 2 surface also can be standard ball shape structure, and internal layer 2 forms sliding friction surface with liner overcoat 4 and mortar cup liner 3.
Internal layer in structure provided by the invention passes through liner overcoat and the mortar cup interliner of polyether-ether-ketone (PEEK) or derivatives thereof, reduces stress and concentrates, also suitably add the rigidity of mortar cup.
Be combined with internal layer again by the liner outer sheath covers mortar cup liner of PEEK or derivant in structure of the present invention, the coupling requirement of hard liner can be met, the coupling requirement of soft liner can be met again.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in the claims in the present invention.
